Abstract

The invention relates to a fuel cell block (40) that comprises elements (1, 25a-b, 42a-e, 51, 52) that are stacked. At least two adjacent elements (1, 25a-b, 42a-e, 51, 52) define an intermediate space (7, 27, 71) between them. Radial channels (8a, 8b, 8c, 35, 72, 76) are configured between the two elements (1, 25a-b, 42a-e, 51, 52) or in one of the two elements (51, 52), said channels communicating with the intermediate space (7, 27, 71). At least one of the radial channels is configured as a blind channel (9a, 9b, 74, 77) and, unlike the radial channels (8a, 8b, 8c, 35, 72, 76), is not used for a medium flowing into or out of the intermediate space (7, 27, 71). The number of radial channels that are configured as blind channels (9a, 9b, 74, 77) influences the quantity of operating medium flowing through the intermediate space (7, 27, 71).
